Hey guys, I’m having some trouble finding the exact quantity of energy storied in this spring problem.
It’s like a problem with parts A and B, part A says "Determine the amount of work required to stretch the spring from 0 to 20 cm. I found that to be 125J. For Part B, it says "Suppose that this spring was stretched 7.753 cm. Find the exact quantity of energy stored in the spring.
2. Relevant equations
I think that the equation that i would use is the one for elastic energy, Ee= 1/2kx^2
3. The attempt at a solution
So far i have Ee= 1/2kx^2
I’m not sure if i’m doing this right, or what to do next.
